Numerical calculations and simulations

CFD is a numerical method to calculate flows in systems of arbitrary geometry (Computational Fluid Dynamics). The entire flow field is divided into small elements. The velocities and scalar quantities such as temperature or smoke concentration are calculated in each element.
